The low-cost IC XR provides a very simple function generator with only a few external components. The DC bias at this input is necessary, and the signal amplitude must be properly adjusted. The XR has some interesting features that illustrate some of the topics mentioned in this page, so let’s examine this chip. Many attempts have come out with this simple circuit. One could make a small AM radio transmitter with this chip for use over short distances.
Modulating the frequency with an external datawheet has quite a few applications. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.
For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.
Use a buffered potentiometer to test the dependence of frequency on VC. The output waveforms can be both amplitude and frequency modulated. R is the normal timing resisor, while RC handles the modulating current.
Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment to minimize distortion of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – 2MHz XR Function Generator Kit. The output can be buffered to adjust its DC component and signal amplitude. XR data sheet provides complete basic circuit for a simple function generator.
An increase in V lowers the frequency, and an increase raises it.
Although this is an analogue IC, this project just made it into the Arduino section of my website because oc uses an ATmega as a frequency counter and to drive an 8-digit 0.
There are integrated circuits that produce sine waves, although they are really relaxation oscillators dtaasheet the sine waves come from shaping a triangle wave.
On the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with alligator clips. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.
You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of. The capacitor C and the power to determine the frequency at pin 7.
The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms. FM would also be good for testing a phase-locked loop. The waveform looks like a spring extending and contracting! Function Generator with XR The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
At pin 3 to set the exact medium voltage and the output amplitude. There are actually two timing resistors, and which one is used is selected by the level on pin 9. In any case, do not exceed 3 mA from pin 7 or 8. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.

This circuit sets the average value of the output waveform here to 6. The actual sample structure differs in some details from the data datashdet. Frequency can be varied by a range switch and a potentiometer, so that one could make a fairly useful function generator based on this chip, at low cost.
It requires an operating voltage of 12 V and delivers sine and square wave signals. The proper adjustment of these controls is necessary for a good-looking sine wave.
